My favorite manager went looking for important problems on the team that nobody was taking responsibility for, and ensured that they would get addressed. If you mentioned something to them in passing that was an issue, they next week they'd have taken some action to follow up on it. They promoted a collective decision making process, but also made sure that decisions got made, rather than languishing in a no-man's land. And, of course, they were respectful, welcoming to new team members, and had the technical knowledge to understand what was going on on the team.
